HIV Ag/Ab Screening
Antibody tests check for HIV antibodies in blood or oral fluid. HIV antibodies are disease- fighting proteins that the body produces in response to HIV infection. Most rapid tests and home use tests are antibody tests. Antigen/antibody tests can detect both HIV antibodies and HIV antigens (a part of the virus) in blood.
